DerBar - a simple system-status bar
is a simple, slightly-configurable status bar for monitoring key system and
network parameters. It is modeled on older status-monitoring
programs such as StatBar, WinBar, and InfoBar,
but without the configuration options of those other programs; it is
designed for compactness and compatibility, not for turning parts on
and off. The few configuration options that are
present, are accessed via the icon in the system tray. You can
move DerBar anywhere you want, by grabbing it and dragging it around,
and it will remember where you leave it next time it runs.
DerBar is compatible with all other programs and will not
conflict with DirectX games, as each of the afore-mentioned tools would
sometimes do. It works fine with WinXP and Vista, and works on
Linux under Wine, but I have no idea whether it would work under Win98 or not.
DerBar is freeware, source code is available.

Background on this program
I've always been a fan of small, low-profile system-status bars. The first one I used was StatBar,
a configurable tool that displayed CPU Utilization, memory, and various
other common system parameters in an attractive, slim bar. It
mostly got along with other programs, though it would bleed through
into certain DirectX displays. Unfortunately, support for the
program vanished in 2005. When I finally got a computer with more
than 2GB of RAM, I discovered that 2GB was all that StatBar could
display. So a replacement was needed! I looked at WinBar,
which also looked nice, but it had exactly the same limitations as StatBar
(no support, 2GB memory limit). There were other programs that did
similar jobs (SysMetrix and RainMeter come to mind), but they were much
larger programs both in file sizes and screen sizes, and I wasn't
really happy with them.
Then I discovered Night Iguana's InfoBar.
It is freeware, configurable, and looks really nice, and supports
>2GB RAM. I thought I'd found my perfect solution.
Unfortunately, it has a variety of quirks to it (mostly related
to DirectX interactions). These quirks can be largely avoided by
minimizing the program, but I never remember to do that before firing
up a game. Support does exist for InfoBar, but finally I
decided it was just easier to write my own.
My support guarantee
And so, DerBar
was born. I don't promise any better support than any of the
others, but the source code is available, and you can do what you wish
with it. My only request is that, if you distribute a modified
program, please change the name to something else to avoid confusion.
DerBar is written in C, using standard Win32 library calls, to improve compatibility. It is built using the open source MinGW (Minimal Gnu for Windows) tools, and requires a couple of the common utilities from Cygwin as well (Gnu make, rm, etc).
